Born to measure things, forced to explain that metrology is not the study of weather.

Happy World #MetrologyDay π₯³Here's a sub-ppm 20kA direct current comparator by Measurements International in the 90s based on a design by Kusters from the 60s. Single primary winding, matched cable lengths for uniform magnetic field, new readout electronics developed at CERN

is there an easy way to back up a bunch of DC100 cassette tapes with firmware options? π¬

been a while since I met electronic test equipment whose purpose I have absolutely no clue about

it's been a while but TMC4671 is still so impressive

Are there any experts on oxygen-assisted fiber laser steel cutting here? I can't seem to get this thing to behave. My best results in 6mm mild steel came out of 0.5 bar, 90% power, 15mm/s, 0.5mm standoff, -2mm nozzle focus, and an excessively long initial pierce to be safe

I suspected my cheap oxygen pressure regulator at first and got an electronic SMC one (no regrets, it's cute) but it didn't fix it. When cutting circles I get different landscapes in the walls depending on direction, which points towards poor beam centering, but it seems good

only suspect left to check: the focus following. capacitive distance sensing in the midst of molten metal, plasma, sparks, blobs of dross, extreme heat .... sound like a nightmare for electronics, maybe it gets confused and oscillates?
